CLAUDE POST, OF CHICAGO, ILLINOIS INKINGr-ROLLER.

Application filed February 19, 1921.

ful Improvements in Liking-Rollers, of

which the following is a description.

My invention relates to improvements in inking rollers, and more particularly to an inking roller having an ink-receiving reservoir therein which may be conveniently filled, and being provided with means whereby the ink in said reservoir may be fed to the inking surface at any desired rate of flow.

Another object of my invention is to provide a device of the character described which may be easily assembled and disassembled for inspection or the like, and which is extremely simple, durable, compact, economical, efficient and satisfactory for use wherever found applicable. Many other objects and advantages of the construction herein shown and described will be obvious to those skilled in the art from the disclosure herein given.

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed out in the claims.

In the drawings, wherein like reference characters indicate like or corresponding parts,

Figure 1 is an elevation of my device;

Fig. 2 is an end view of the same;

Fig. 3 is a section taken substantially on line 33 of Fig. 1; p

Fig. 4C is a section taken substantially on line H of Fig. 2;

Fig. 5 is an elevation of a modified form of my device;

Fig. 6 is a section taken substantially on line 66 of Fig. 5;

Fig. 7 is a section taken substantially on line 77 of Fig. 5;

Fig. 8 isan end vlew of the device shown in Fig. 5; and

Fig. 9 is a fragmentary section taken sub stantially on line 99 of Fig. 8.

Referring to the drawings, A. designates the inking roller in its entirety, said roller comprisin a main body section 1, having a convex cylindrical surface which has been cut across on achord 2. An ink-receiving Specification of Letters Patent.

'Patented Nov. 29, 1921.

Serial No. 446,363.

reservoir R is provided in said roller and extends substantially the entire length there of, said reservoir being of any desired shape,

preferably as shown in Fig. 3, and having its open side at the chordal surface 2.

Adapted to be detachablysecured to the roller 1 is a cover 8, said cover extending across the reservoir, and having its periphery convex and of a degree of curvature equal to that of the inking surface of the;

roller 1 so as to cooperate therewith to form a substantially cylindrical inking surface for said roller, the inner or flat chordal sur face 4 of said cover being preferably tapered toward one of the edges which intersects the segmental surface so that it forms an outwardly divergent aperture with the chordal surface of said roller 1, for a reason to be hereinafter described.

Between the cover 3 and roller 1 is a thin resilient spring plate 5, preferably of metal,

said plate extending across the reservoir and being secured along one edge between said cover and plate by screws or the like 6 extending between said cover and roller 1.

The forward edge of said plate is preferably adjustably movable between the divergent chordal surfaces of the roller and cover so as to vary the extent of the opening of the passage between the inking periphery and the reservoir B, said adjustment being preferably obtained by providing adjusting screws 7 extending through said cover, as shown in Figs. Qand 3, and bearing on the plate 5 so that these screws may be manipulated to increase or decrease the width of the'opening of the passage, and thereby accordingly regulating the amount of ink flowingtherethrough to the inking periphery.

A chamber B extending substantially the length of the roller and either open or closed atits ends is preferably provided adjacent said reservoir so as to maintain a proper balance of the roller, said chamber and reservoir being separated by a longitudinally extending median wall 8. If such a chamber were not provided, the center of gravity would be out ofv line or to one side of the rotational. axis of the roller, and thus the roller would quickly-wear in its bearings and also would tend to harm the composition rollers against which it bears.

The ends 9 of the reservoir R are closed, and in either one or both of its end walls are provided closure plugs 10 or with equiva- 1 for instance by pressure devices similar to grease guns. 1

In the modification shown in Figs. 5 to 9, I have provided another form of cover securing means. A pluralityof recesses 11, preferably one at each end, as shown 1HF1g. 5, are provided through the web 8 of the roller 1, said recesses being of a size to receive locking bars 12 which are secured to one end of the cover by any suitable means, such as screws 13, the ends 14 of said locking bars being hooked and havingarcuate recesses 15 thereinadapted to engage the cooperating bearing lugs 16 and prevent move ment therebetween, said lugs being arranged on the roller so as to project into the chamber B and having arcuate ends to engage the arcuate recesses 15 of the locking bars so that when the cover is placed in position the cooperating lugs and bars will hold it in place. The recesses 11 may be enlarged at their outer ends as at 17 so that the locking bars may have a lateral or pivotal movement therein during insertion and removal, and thus permit the assembling and disassembling to be more readily effected.

The resilient plate 5 is secured to the cover by screws 18 or any other equivalent means for the purpose, there being an adjusting screw 7, as in the previous modification, bearing on the plate 5, for adjusting the extent of the delivery opening. In order to more securely prevent displacement between the cover and roller, I have provided at the end of the cover opposite to that upon which the locking bars 12 are positioned, a latch 19, secured at one or both ends of the cover by screws 20 or other equivalent means for the purpose, the free end of said latchhaving a pin or offsetQl projecting inwardly therefrom and engageable in a recess 22 provided in the roller.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention; hence I do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described, or uses mentioned.

hat I claim as new and desire to secure by Letters Patent is:
